"Ahh... when can I take a break, ma? I'm getting tired..." Nobara said as she chugged water and flopped on the ground.
Yup.
You were a complete mama bear. Nobara was your only child, so it was only natural for you to be protective of her. But you knew you wouldn't be there to protect her all the time, so you've been training her. Maybe a little too hard though...
It was tiring, yes. But Nobara knows that her mom does it out of concern for her, even if you won't admit it. Her mama's a tough cookie, just like her. She'd definitely thank her mom later on when she can use these skills in handy.
After a while, Nobara stood back up and stretched a bit. She was obviously sore, so you were contemplating whether or not you should give her a break or not.
